To name a few potential __attribute__ candidates. - access (read_only, 1) - aligned - aligned (alignment) - always_inline - noreturn - nothrow - pure

- aligned - aligned (alignment) Now there are 3 ways to align in gcc: #pragma pack _Alignas __attribute___

Currently doing all but `access`. The access modes are read_only, read_write, write_only, or none. https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html None of those access modes are supported in detail by D semantics, the best we can do without adding more D semantics is to simply ignore them, which is done today. I.e. there isn't much value in implementing `access`. I'm going to write the rest as "FIXED" and `access` as WONTFIX.
